What I find really interesting about gravity, it that Gravity Waves are not included within the Einstein Equation, in that on the left side we have the Einstein Tensor (consisting of the Ricci Tensor, the Metric, and then the Scalar Curvature), then on the right side we have the Energy Momentum (consisting of the 8xPi, the Gravitational Constant, and the Energy Density).
But gravity waves are separate, they run only within the metric tensor, and as such energy within a gravitational field cannot be conserved, unlike electric and magnetic fields.
SO, this means that gravity waves slip underneath the gravitational field (geodesics) without being affected…we see this in Black Holes, where nothing can escape them, not even light, but the mass of a black hole creates gravity waves which can and do escape.
This is totally bizarre, and in some part, conflicts with special relativity. Remember the forces are carried within the geodesic, within the Christoffel symbols. So how can you detect gravity waves when these quadrapole waves radiate out the metric, underneath the field???

You just can’t because light bends within the geodesic, which again, is governed by the Einstein Tensor, so I don't feel they will be found.
I've said it before, gravity (GR) is a fictitious force, it is mediated by “slippery-trickery mathematics”

and is nothing like the other forces.
It’s as though gravity waves operate through the [dare I say] 'Ether'…
